Despite advances in genomics in recent years, schizophrenia remains one of the most complex challenges of both genetics and neuroscience. The chromosomal abnormality 22q11 deletion syndrome, also known as DiGeorge syndrome, offers a way in, since it is one of the strongest genetic risk factors for schizophrenia.
Out of dozens of genes within the 22q11 deletion, several encode proteins found in mitochondria. A team of Emory scientists, led by cell biologist Victor Faundez, recently analyzed Read more

A recent paper in Neuropsychologia got a lot of attention on Twitter and at the Cognitive Neuroscience Society meeting in Boston over the weekend. It discusses what can happen when the amygdala, a region of the brain known for regulating emotional responses, receives direct electrical stimulation. A thrill ride – but for only one study participant. Two of nine people noticed the electrical stimulation. One individual reported (a video is included in the paper):

“It was, um, it was terrifying, it was just…it was like I was about to get attacked by a dog. Like the moment, like someone unleashes a dog on you, and it’s just like it’s so close…

He also spontaneously reported “this is fun.” He further explained that he could distinguish feelings in his body that would normally be associated with fear recognized and the absence of an actual threat, making the experience “fun”.
